I mentioned the other day in
@Trick's thread about his similar SG9665GC V2 woes that I would describe the current situation with my unit. It is still not clear what exactly is going on but the problem, whatever it is, appears to be with the camera itself and not the cable and certainly not the power supply, having had the issues manifest with three different ones now.
Recently, the camera has been performing quite reliably even in the insanely bitter cold temperatures we've had here lately. One morning the camera booted up and ran just fine with the ambient temperature inside the cab of my truck at º-5 F (-20.55556º C).
Shortly after that, in more moderate temperatures the camera again booted up and began recording at which time I drove off and was on my way when about ten minutes into my journey I looked up at the camera and noticed that the REC indicator was on but no longer blinking. I pulled over to have a look at what was going on and discovered that the camera was frozen up, the screen was black and the buttons were unresponsive. As has been the case all along, after unplugging the camera for a few seconds and plugging it back in gets everything working normally again. Everything worked fine for the rest of the day. Upon returning home I reviewed the files from the day and discovered that the file where the camera had frozen up and ceased recording was corrupted and unplayable. In other words, whatever occurred happened mid loop. This failure is new behavior not reported earlier.
This situation is becoming untenable. It's one thing to have to manually reboot the camera once or twice a day until I am able to install a suitable replacement but having the camera freeze up and stop recording unexpectedly during my daily travels when I may not even notice is not cool.
The fact that this issue is intermittent and that it might not happen for days or even weeks on end is infuriating. I almost wish the camera would go ahead and just croak already.
